Radiation Dosimeter DRGB-90
Price: US $97.00 (including the shipping price)
The DRGB-90 radiation dosimeter gives audible and visible measurement of levels of radioactivity (photon rays, hard beta-rays and hard-gamma rays). It can be used to check the background radiation in a house or workplace and check for contaminated products or food. The dosimeter is intended for use at temperatures from 263 to 313 °K (-10 to 40 °C, 14 to 104 °F).
The radiation dosimeter is used as a portable handheld device. The case is made of shock-resistant polystyrene. Its indicators are red and green LEDs and an audible clicker.
Measurements of a level of radiation make on two scales. One (top) scale is for measurement of a level of radiation in microsievert. This scale has three parts. A green part is the presence of radiation levels comparable to the natural background. The yellow part is the presence an allowable level of radiation. A red part is the presence a dangerous zone.
Other (bottom) scale is for measurement of a level of radiation in microroentgen.
This dosimeter contain a Geiger Counter
Time of measurement is no more than 60 seconds
The power supply consists of three AA batteries
One set of batteries will operate the radiation dosimeter continuously for at least 300 hours under natural background radiation conditions
The radiation dosimeter weighs is 0.25 kg (7 ounces avoirdupois)
